Expanded memory : Memory used through EMS. In systems based on
Intel 80386 or later processor expanded memory is part of
the extended memory that is mapped into the expanded memory
page frame by the processor. The mapping is controlled by
the EMM. In earlier systems, a dedicated EMS hardware
adaptor is needed to map memory into the page frame. In both
cases, an appropriate device driver is needed for the proper
communication between hardware and EMM.
